BERKELEY (KCBS) – It's being called the most mysterious star ever detected, and now University of California, Berkeley astronomers are trying to determine if aliens exist on it.

"Tabby's Star" dims irregularly for days at a time, which has prompted speculation that some sort of structure, possibly built by extraterrestrial life is orbiting the star.

Astronomers at Berkeley are using two of the world's biggest radio telescopes to get to the bottom of the mystery.

People anticipating alien life shouldn't get too excited, as chief scientists on the project say there's about a one in a billion chance that the structure was built by aliens.
